To all whom it may concern: a

Be it known that I, CHARLEs B. JOHNSON,

a citizen ofthe United States, residing at Paterson, in the county ofPassaicand State of New J ersey, have invented certain new and usefulImprovements in Machines for Treating Fabrics. of which the following isa specification. i

This invention relates to machines for ad-.

One part of my invention consists inlnovel means for effecting theadvance ofthe material in its own plane; another part con sists in anovel means for controlling the relation between the material and meansto operate thereon, as brushing means, par

ticularly with reference to reversingthe die. rection of traverse ofthe: material 1 another part consists in novel means for controlling ithe relation between the material and means to operate thereon,as'singeing means, par-.

ticularly with reference to stoppingfand starting the advance of thematerial; another part consists in novel means for disposing of theproduct, as the charred lint, ofthe brushing operation. The inventionfurther con sists in certain combinations and arrangements of partswhereby various operations necessary to reverse the machine a're all ef-.fected from a common control means.

My invention is shownherem 1n connec: tion wlth-a machinefors1nge1ng-andhrushingfabrics wherein the fabric isadvanced in its :ownplane from; one end .to the other thereoffirst in one. and then inthe-other direction past a singeing means and alsopast two brushingnie'ansrarranged on relatively! opposite sides of the slngeing means andso controlled that in which ever-direction the fabric is advanced" thebrushingmeans first approached will be inactive and the other active. 1q

a is a suitable frame having atthe front bearings for a horizontaldrive-shaft I) having a pulley 0 whereby it is driven. and splined to ita friction wheel dswhich may be shifted thereon by a screw 6 journaledin the frame and carrying a nut suitably engaged with the frictionwheel. At right angles to shaft 6 there is journaled in the frame ashaft '9 movable in its bearings toward and from shaft Z) to bring theface plate 7L thereon into and out of driving contact with the frictionwheel. The thrust of shaft 9- toward shaft 6 is accomplished through alever 2' (Figs. 2, 4: and 5) from a cam on a shaft is jouriialeol,parallel with shaft 5, at the back of the machine. The speedof shaft 9may be varied by adjusting tllie friction wheel with respect to the facep ate.

Parallel with shaft 9 and at opposite sides of the frame there arejournaled two rolls Z which are driven in relatively opposite directionsby sprocket-and-chain connectionsflfronrthe shaft 9, i. e., a sprocket mon one roll and a sprocket n on said shaft are connected by achain 0,and a sprocket 79 (Fig. 4) on the other roll and a sprocket g on acounter-shaft r are connectedby a chain 8, shaft 9 and counter-shaft 1having intermeshing pinions t-u, respectively. The fabric extends overthe rolls 1. Over each roll Z isa pressure roll 4) journaled in abracket 'w fulcrumed' in the "frame. The brackets form a part of atoggle means whereby when one roll '0 is allowed to bear on thecorresponding (continuously rotat ing) roll .Z' the other will beelevated out of r .coactingrelation to the corresponding (continuouslyrotating)" roll Z. Thetoggle means includes? a rocker consisting of atransverse shaft mcarrying a pair of V-.. shaped cranks/y, and links 2connecting corresponding arms of the cranks with the:

levers. w (Fig. The rocker has also a crank or arm 2, andgwhen it ismoved one Way or the other by means (to be described) connected withsaid arm 2 it will obviously cause one roll 1) to be elevated and theother depressed. In practice, the right hand advancing means serves tofeed the fabric to, the right, at which time the roll 4) thereof. iscoacting with its roll Z, the roll a: of the other advancing means beingelevated and 4) holds the first in effect locked against withdrawal andpressing against its roll Z.

In accordance with the well-known principleof machines of this type theleading end of the fabric is wound on-a take-up beam, there being twosuch beams,- one for each end of the fabric, and there are clutcheswhereby the beams may be disconnectively connected with meansforrotating them, so

that one may be driven to wind up the at vancing endr'of the fabricand-the other run free todeliver the fabric. The beams are eachremovably supported at one end- (being suitably journaled at the: otherend in the frame) by a head stocklor mandrel 3 (Fig;

6) ijournaled in the frameand carrying, revoluble thereon, adriving'clutch member a and splined thereon a driven clutch memi beriorfork 5 adapted to: be shifted by a bell-crank lever 6 into andout ofclutching engagement with the member 4. hlember a, which is also apulley, 1s drlvenicontlnuously from a pulley 7011 the adjoining roll Zthrough the medium of a belt There-V .is a stirrup rod 9 having;a{universal-joi-nt l connection. with each bell-cranlrleyer 6 and itcarries a cushion spring10'and above the spring a collar 11, the objectof which will be explained later.

is pairof parallel levers, one at each' side of and sultably fulcrumedin themachlne, and-13 a bar pivot-ally connecting them and also pivotally connected with the rocker arm' 2 andihavingits movement withthe levers in each direction dim-fired by a;

springstop 14L engaging insuitable notches in the bar (Fig.1). a Thelevershave out-f wei dly projecting cranks 1.5 to which are pivotedcollars 16 penetrated by the rods 9 and interposed betweensprings 10 andcollars llithereonm hen the: system of parts 12, 13 :isshifted'to buckleone and straighten a the other toggle connection, thus depressingoneroll a and elevating. the other roll} 0, the rod 9 corresponding tothefirst toggle connection will be depressed and the other elevatedto'respectively engage and disengage the corresponding driven clutchmembers 5 with respect to the (continuously rotated) clutch members l.The cushion spring 10 allows yielding should the fork 'be forced inwardwhen opposite the lugs 4 of the driving clutch member.

There is a pair of horizontal suitably cooled guide rollers 18 arrangedin the verticalicentral front to-rear. planeofthe machine,andfulcrumedon axes in this plane is a pair: of singeing devices 19, one below eachroller 1-8, the Vdevices 19 have reversely projecting cranks'20 whichareconnected by a link 213so that thessingeing devices may be conjointlyshifted on their fulcra'into and out of operative relation to therollers 18 which, as will be understood, afiiord a suitable backing forthe fabric while being singed- The shifting? ofvthe sin geing de vicesis efliectedfromthe shaft by aworm 22 thereon and an arnr23 onthe lowercrank 20, the arm 23 having a roller Ql-engaging the worm (Fig. 8).Shaftlc is turned in one direction .to start and in the other directionto stop the machine, through the medium of parts j, g, h and-, by themeans whereby the. system of parts including the singeingi devicescareconnected "with; saidshaftIZc, when the latter isrotated to stop themachinefthe singeingdevices are shifted out of'pos-ition for singeing(where, with the fabric stationary, it would ofcourse be burned). andwhenit is rotated to startthe machine they are shifted into position forsingeing. r 1' it At leach endof the machine there-is a pair of: levers'25 having their upper and lowerendsiconnectedby the pairs of links 26;A parallel lever system is thus formed; Eaclrpair; of links carries twoguide rollers 27, one near each end thereof Thefabric A in thepresentinstance extend-s under and over the lower-and upper'right-handguiderollers 27,1'espectively, then; under the lower guide-roller -18,thenover anidlerrollerEZS,F

thenunder the guide-roller 18; then over an i idler roller 29, and thendown to the right side of-the -left-hand guide-rollersf27. The pairs ofupper and lower rollers27, one'pair at the right and the other at theleft, afford means to maintain separatetautstretches A of the fabric,and on shifting the parallel lever systemon itsfulcra said stretcheswill shift from the planes indicated by the solid lines tothosefindicated by the dottedlines inF1gn3'. This has to do with thebrushing means, and a "further explanation thereof,

n'i eonnectionwvithf S means: will follow The shifting ofthelever-system iS y nated with thereversing of the directionof advance ofthe fabric by the following" means 30 is a lever fulcrumedin the frameits other end connected with the lever system by the link 33. T o varythe throw of the lever system pin 31is adjusted in the. slot of lever30.-- i

. The brushes 34 revolve on horiz ontalaxes a to which an exhaust meansmay be attached.

V the left-hand roll 1.

and are contained in housings 35open to-- ward the fabric. Eachhousingjis also provided with a delivery outlet 35 at one end,

So far as I am aware this feature is new in machines of this kind, inwhich-space is wasted by exhausting means being'attached radiallyinstead of axially of the housing in the usual construction. -Each brushhas a pinion 36 and the several brushes are continuously rotated througha chain 37 from a gear 38 (Figs. 1 and 4) fixedtorotate with There arefour brushes, a pair (relatively-to the length of the fabric) on eachside of the singeing means. The'brushes in each pair are adapted tobrush the opposite faces of" the corresponding stretch A ofthe fabric,and such stretch and the plane in which "the axes of the brushes lieform edgewise an X. The two lower brushes are betweenthe stretches andthe two upper brushes outward of them.

Whenthe parallel lever system is shifted one'way or the other from bar13 it will be apparent that each planiform length or stretch A will movefrom one to the other of the solid and dotted line positions thereofshown in Fig. 3, so that according to the direction in which theshifting takes place it will be moved'into contact with or away fromeach of the corresponding brushes. By placing the pair of lower brushesbetween and the pair of upper brushes outward of the stretches A theshifting of the lever system in either direction brings one stretchagainst its brushes and the other clear of its brushes." The connectionsbetween the lever system and thebar Bare such that according to thedirection in which the fabric will be advanced the brushing means thatis approached by the fabric after passing the singeing means will beactive and the other rendered inactive (so'as not to brush and thusabradethe fabric tono purpose) Varying the throw of the lever system byadjusting pin 31 in lever 30 changes the degree of pressure of thebrushes on the fabric; thispres'sure'may'be alto;

gether eliminated by adjustingthe pin into coincidence with thefulcrum-of lever 30.

- now be apparent. Having arranged two stretch (A) shifting meanscorresponding to the empty beam will be active and the correspondingmeans appertaining to the full beam will be inactive. Shaft I) being inrotation, shaft is is turnedto move the face plate against the frictionwheel and throw into action the singeing devices. From now on, until theprocess is completed, the two rolls Z, driving clutch members 4 and thetwo sets of brushes remain continuously rotated. Each time the fabrichas been un-, Wound from one beam and wound up on the other the operatorreverses the machine by shifting bar 13 so that the advancing means,beam and brushes that were previously active become inactive and theother corresponding parts become active, repeating the reversing processas many times as may be necessary in order to complete the singeing. I

Suitable means is employed for supplying a combustible to thesingeingmeans and a cooling medium to the rollers 18, but these form nopart of my invention.
